VALVE FOB, RADIATOBS.

To all whom it may concern: a I Be it known that I, WALTER C. BOYD, a citizen of the United States, residing at Shepherdsville, in the county of Bullitt and State of Kentucky, have invented certain new and useful Improvements in Valves for Radiators, of which the following is aspecification.

' This invention relates to valves and the primary object of the invention is to provide an improved valve for radiators, which is so constructed vas to eliminate the water hammer in radiators and the usual type of air valves now in vogue, which is easily displaced and disarranged. e

Another object of the invention is to pro vide an improved type of valve for radiators, which permits effective use of the one pipe system for radiators, therebyieliminating the return pipevan d the freezing of the water of condensation and permitting ofthe free lengthening or shortening of the radiator, and which is so constructed as to provide a relatively large passage arranged ina vertical plane for the water of con densation and theheating elements, thereby eliminating the water hammer in the pipe.

.A further object of the invention is to provide'an improved radiator. valve for controlling the flow of the heating element and the water of condensation from and to a radiator having an air valve located in the stem thereof, so as to prevent the tampering and disarrangement of the air Valve.

A further object ofthe invention is to provide an improved combination radiator valve having a divided body for the'flow of the heating element and the water of condensation, the passage for the water of condensation having a pipe connected thereto which is adapted to extend into the rear portion of the radiator, so as to permit the water of condensation to enter the valve only at this point. I

A further object of the invention is to provide an improved radiator valve having a water seal therein, so as to prevent the escape of air into the radiator pipe and to permit the same to pass out of the valve located in the radiator valve stem. A still further object of the inventionis Specification of Letters Patent. Patented Aug; Application filed June a, 1920. Serial No. 387,428.

to provide an improved radiator valve of the above character which is durable and efiicient in. use, ;one that is simple and easy to manufacture, and one which can be placed upon the marketat a reasonable cost. WVith these and: other 1 objects in view, the invention consists in the novel construction, arrangement and formation of parts,

as, will be hereinafter moreyspecifically described, claimedand illustrated ingthe accompanying drawings, forminga part of this specification, in which drawings Figure 1 is a side elevation of a radiator showing parts thereof in section having the improved valve connected thereto.

Referringto the, drawings in detail the water of condensation being shown wherein similar reference characters designate correspondingparts throughout the several views, the letter A indicates aradiator, B, the supply pipe therefor, andYC, the

improved radiator valve. g q

The radiator A is of the ordinary or. any preferred construction and includes .the outer sections 10 and 11, and the intermediate sections 12. The end sections 10 and 11 and the intermediate section 12 are'connected in the usual manner by nipples or the like 13. I v i Yhe supply pipe 13 extends from the boiler or other point of supply in the usual manner and is connected bymeans of an elbow joint 14; with the improved valve C. r

. The improved valve C includes the casing or body 15 having reduced terminals 16'and 17. The terminal116 is internally threaded for the reception of the'supply pipe, B.

The terminal 17 is externally threaded as at 18 and is threaded into the end radiator section in the ordinary manner. The upper end of the valve casing is open and provided with an externally threaded neck 19, which is closed by the internally threaded bonnet 20, which rotatably carries the valve operating stem 21, which will be hereinafter more fully described. The bonnet 20 is provided with a suitable packing 22, which is held in place by the packing nut 23, which engages the valve stem and is threaded into engagement with the bonnet 20 by means of the internally threaded lower extension 24 which engages the upwardly extending an nular'flange 25 formed on the bonnet. The bonnet 20 around the upstanding annular flange 25 is provided with an annular depression 26 in which the lower edge of the packing nut 23 is adapted to fit.

The upperterminal of the'packing nut 21 is provided with an upwardly extending annular flange- 27 in which is rotatably fitted the depending annular extension 28 formed on the operating handle 29. The operating handle-29 isprovided with a non-heat conducting hand grip 30 which is'held in place by a suitable set screw or the like 31. The operatingstem 21 for the handle 29 is formed hollow for the reception of the air valve 32, which includes the valve seat The valve seat 33 is fitted in the threaded bore-35ofthevalve stem 21-. A loch. screw 36 is provided for holding the handlein operative position on the valve stem 21 and this screw isprovided with a central passage 37 for the air which is located directly above the passageformed in the valve seat 33. A needle valve38 is adapted to'fit on the seat and to close thesame and this valve is carried by a hollow float 39 which is of substantially cylindrical formation. The float 39 is reciprocably mounted in the enlarged lower end 40 ofthe'rotatabl'e valve stem 21. The-lower end of the enlarged portion 40 of the valve stem is rotatably fitted in an opening 41 formed in the transversely extending horizontally disposed partition plate 42 which extends parallel with the longitudinal center of the valve casing and extension or terminal 17. This partition 42 is arranged in a horizontal'plane and ends short of the terminal 16 and is provided with the downturned vertically disposed lip which terminates below the level of the water of condensation so as to prevent the escape of air into the supply pipe 13' and thus force the same to make its exit into the atmosphere. The horizontally disposed partition 42 divides the valve casing into apair ofcompart'ments or passages 44 and 45 which are respectively for the passage of the heating element and the water of condensation and the passagefor the water of condensation is provided with an internally threaded end 46 in which is fitted the inwardly extending pipe 47, which is positioned in the radiator A. The pipe 46 terminates short of the outer radiator section 11, and is adapted to collect the water of condensation therefrom. The terminal 16 of the valve casing 14: has formed thereon the vertically disposed valve seat 48 on which is adapted to seat the circular valve 49 which is adapted to be moved into and out of engagement with the seat, by means of the connecting link 50 which is ro tatably mounted around the cam 51 formed on the valve stem 21 adjacent to its lower end. The connecting link 5O carries a ball end 52 which is swivelly connected to the valve 49 by means of a nut 53', which holds valve, an operating handle for the valve The outer face of the valve carries a removable seat 54 such as leather, fiberyhard rubher, or the like. The valve 49 is silded into and out of engagement with the seat 48 upon operation of the stem by suitable horizontally disposed ribs 55 which are received in grooves 56 formed in the side edges of the valve 49. The operating handle 29'opposite to the hand grip 30 is provided with a radially extending downwardly disposed indicator 57 which is adapted to cooperate with a dial 58 formed on the upper surface of the bonnet 20. The dial 58 includes aplurality of spaced equi-distantly disposed'l'ugs59 and the lugs are arrangedon opposite sides of the body at the longitudinal center of the casing have scribed adjacent thereto on and off as at 60 so as to indicate the open and closed position of the valves.

In operation of the improved valve the valve 30 is moved until the indicator reaches the lug 59 adjacent to which is scribed the word on which rotates the valve stem 21 and the cam 51 thus moving the link rearwardly and moving the valve49 from its seat 48. This permits the heating element to ride into the casing and owingto the water seal the same will take its course through the passage 44 and then into the radiator in the ordinary manner. As the steam or heating fluid enters the radiator the same will force the air or water of condensation to the rear portion of" the radiator and then into the pipe 47 and into the passage 45. The air will then ride around the float 32 andout of the passage way 37. If the level of water of condensation rises the float will be carried therewith and thus close the air valve and prevent the escape of the water of condensation therethrough. After the air has been driven from the radiator the steam or other heating fluid will flow into the pipe 47 and the passage way 45 and around the float 32. This will heat the air confined in the float 32 and expand the same which will seat the valve and thus prevent the escape of steam from the radiator. The valve 49 may be closegl or partially closed according to the amount ot'hcat desired. I r I From the foregoing description it can be seen that an improved combination radiator valve has been provided, which effectively eliminates the ordinary type or air escape valve now in vogue and permits the effective use of. onepipe system or" radiators and eliminates all water hammers in the radiators and pipes.
